Abstract

The term “patent” is an abbreviation of “letters patent”, the open form of document historically issued by the Crown for the purpose of conferring a right or privilege or otherwise communicating the royal will. In contemporary law it denotes the species of intellectual property that is granted as an inducement for the creation and disclosure of novel, inventive and industrially applicable inventions. In the UK that property is conferred under the Patents Act 1977, or with similar effect the European Patent Convention (EPC), and comprises the exclusive right to use and sell a protected invention for up to 20 years. A protected invention may be any subject matter having technical character; a definition derived from the Act’s express exclusion from patentability of (among other things) discoveries, scientific theories, business methods and computer programs “as such”. Also excluded are surgical, therapeutic and diagnostic methods (for lack of industrial applicability), and inventions the commercial exploitation of which would be contrary to public policy or morality. In these and other respects the Patents Act follows the EPC, which it was the explicit purpose of that Act to implement. Patents are territorial, and are thus only valid and infringed in their country of issue. For a UK inventor to obtain protection outside the UK s/he must therefore obtain a patent from that country, either directly by applying under its laws, or if it is a party to the EPC or other intergovernmental agreement, indirectly by applying under that agreement. Inventors seeking protection for an invention in more than one country will often do so by means of the Patent Cooperation Treaty.
